Why EcoPulseIQ
Most UK hotels are further along than they can demonstrate. The recycling is separated, the boiler was replaced, somebody wrote a policy. What is missing is a measurement anyone else would accept — and, increasingly, being unable to produce one is a legal problem rather than a marketing one.
This page is about why the number we give you is worth anything. It is also about what we refuse to claim, which is the shorter and more useful list.
The situation
None of these need a statistic to be recognisable. If more than two describe your property, the diagnostic will tell you something you do not already know.
Green Key, Green Tourism, GSTC, Hotel Sustainability Basics — each publishes its own criteria, in its own language, aimed at its own idea of a property. None of them will tell you whether you are closer to one than another, because none of them has looked at your hotel yet.
Waste transfer notes in one inbox, half a year of utility bills in another, a training register on somebody's desktop, the linen policy in a document last opened by a manager who left. The work has usually been done. Assembling proof of it is the job nobody has time for.
A published criteria list is a specification, not a diagnosis. Reading it end to end tells you what a scheme wants; it does not tell you which parts you already meet, which you nearly meet, and which have not been started — and that is the only question worth answering before you apply.
An engagement produces a report. The reasoning behind it, the working, and the ability to redo it next year usually walk out of the building. When the scheme revises its criteria, or a corporate client asks a question, you are buying the same work again.
The CMA's Green Claims Code sets out how environmental claims to consumers must be substantiated, and the Digital Markets, Competition and Consumers Act 2024 gave the CMA direct enforcement powers over consumer protection law. “We are committed to sustainability” on a booking page is no longer costless if nothing behind it is written down.
Reproducibility
A score is only worth showing to a sceptical reader if that reader can arrive at it themselves. Ours is produced by fixed arithmetic over published weights, so the calculation can be run by us, by you, or by an assessor working from the method — and it lands in the same place.
That is the whole reason no AI system touches scoring. A model that is asked the same question twice may answer differently twice, and a number that cannot be re-derived is an opinion with a decimal point on it.
What holds it up
Each of these is a thing the product is structurally unable to do differently. That is what makes them worth stating: a feature can be switched off quietly, and a constraint cannot.
Scoring is one pure function. No network call, no randomness, no model, no AI anywhere in the path. The same answers produce the same number on our machines, on yours, and on an assessor's — not usually, always. That is a property of the code, not a service level.
scoreAssessment() · pure function · no I/O
Every weight and every tier threshold lives in a numbered, append-only ruleset that is never edited after publication. Each score is stamped with the scoring version and the question-bank version that produced it, so a score from months ago is recomputed against the exact rules that made it — not against today's. Changing a weight does not rewrite your history; it creates a new version. The current one is 2026.3.
Append-only registry · every score stamped with its version
The scores table has no client insert path at all. The only way a score exists is a server routine that re-reads your raw answers from the database and recomputes the number itself — your browser never submits one. It is an unusual thing to build, and it is the reason a number from this product means anything to a third party: nobody, including you, can hand-edit it.
No client INSERT policy on the scores table
No question is in the bank because it sounded good. Each one is tagged to what it evidences — the GSTC Hotel Standard, Green Key, Hotel Sustainability Basics, ISO 14001, or a UK legal requirement — and the tags are what drive the gap analysis, so an untagged question would do nothing.

Some well-known schemes are deliberately absent. We do not hold their criteria, so mapping to them would be decoration rather than analysis, and a test fails the build if their names appear in the question bank. The UN SDGs are shown as context for what an area contributes to, never as something we assess conformity to — they have no criteria to conform to. A list of frameworks is only useful if the absences are honest.
Enforced by a test, not by good intentions
A UK legal requirement you score near zero on is surfaced on its own, above the score, as a compliance exposure rather than a maturity gap. It is a flag and not a silent deduction — deducting would mean the published weights no longer reproduce the number. A broad score can hide a specific hole; an assessor will open with the hole.
Compliance flags sit beside the score, not inside it
What gets measured
The weights below are not illustrative — they are the exact figures the engine multiplies by, read from the live ruleset. Areas that do not apply to your property surrender their weight to the ones that do, so a hotel without a pool is never marked down for not having one.
Policy, accountability, targets and data collection — the management foundation.
Consumption monitoring, efficiency measures, renewable sourcing and plant maintenance.
Emissions measurement, reduction targets and travel or offset initiatives.
Consumption monitoring, efficient fixtures, reuse and guest linen programmes.
Separation, measurement, food waste, single-use plastics and circular partnerships.
Local sourcing, supplier standards, packaging and contractual requirements.
Staff training, guest communication, community support and fair employment.
Habitat awareness, wildlife-friendly grounds, chemical and peat avoidance, lighting that does not disrupt nocturnal species, and support for local conservation and community projects.
The limits
A sustainability tool that admits nothing is asking to be taken on faith, which is the position its customers are trying to get out of. So here is the list, in the plainest terms we can put it.
Certification is awarded by independent accredited assessors, and it has to be — the standards governing them require the body assessing a property to be separate from anyone who prepared it. We are the preparation. We assess readiness.
No outcome here is guaranteed, and any tool that guarantees one is telling you something it cannot know. What you get is a measurement, the gaps it exposes, and the order to work through them. What you do with that determines the result.
You answer against written anchors and nobody has audited those answers at the moment the number appears. That is why the top maturity band is set deliberately high — a self-reported instrument skews upward, and a label that leaves the building on a website needs to survive being quoted back.
Uploading a document does not raise a number. Evidence is what an assessor asks for; the score is what the answers arithmetically produce. Letting the two interact would make the score unreproducible from the published method, which is the one property everything else here rests on.
You will not find logos, case studies or figures here, because we have not earned any yet. When there are results worth citing they will be named, with permission, and checkable. A page like this one is exactly where an invented number would do the most damage.
This assessment is designed to help benchmark sustainability practices and prepare for recognised sustainability frameworks. It does not constitute certification.
No card, no login to start. Answer honestly and you will get a baseline across eight impact areas, the gaps that matter most, and anything flagged as a UK legal requirement.
